docs: record the correspondence corrections — grounding, faculties, wonder, consolidation

The architecture docs describe four things the design spec has since ruled out,
and each one is a supervisor invented for something that should be a property of
the substrate: grounding modelled as a subsystem rather than as the edge weight
it already is; faculties modelled as parameters of a read when abduce is a write;
wonder materialized as a maintained manifest when it is the boundary of the
structure; and consolidation implemented eleven times behind tickers when a brain
has no cron job.

Left standing rather than deleted, per the repo's own supersession discipline —
the trail of how the understanding matured is the point. Each stale passage is
marked inline and points at a new 06 §12 that transcribes the corrections and
records the measured consolidation inventory.
